We will certainly continue our step-by-step strategy to diagnosing a swimming pool heating unit by checking out how to do when the light in the command pad on the peak of your Sta-Rite pool and spa heating unit that is labeled “service heating unit” is lit. (We will certainly visit us proceed with the presumption that you recognize every little thing from sector one.) This moment you will certainly need to eliminate the sides from the heating unit just before detaching power to the heating unit to make sure that you could check out the codes on the board attached to the topside. After eliminating the sides, you will certainly see the large topside that is still hooked up to the heating system. Listed below the topside is a steel panel that keeps the topside in place. Under this panel there are 2 securing pins (wedge pins). Carefully get rid of both pins and also save them someplace safe till reassembly. Delicately take out the leading and transform it upside down. You will see a light lit on the board you are considering when you transform the topside over. The light will certainly be beside a code that is written on the board.

The first code that you'll view on the left side of the board will be PS. This is the code for the pressure switch. We covered the pressure button in segment one. If this light is lit go back to section one as well as examine that section. If required comply with the guidelines to change the pressure button.

The following code you'll see on the board is HLS. If you have a controller on the system you will should bypass it currently. You will should thoroughly separate the power from the heating unit. After you make sure that the power is separated, you will have to locate as well as open the high-voltage cabinet. This cabinet is a steel box in the middle of the heating unit. If you are considering the cabinet, there is typically a screw on the leading ideal side. Loosen the screw and also the door will swing down towards you. You have to be remarkably careful when operating in this box and also simply do so when you are sure that the power to the heating unit gets out.

You will have to bypass the firewall program safety interface. To do this you will require a brief wire with stab-tab adapters. If you have a controller and also it was properly installed the wire might have been left in the box by the tech which mounted the controller. If not you will should make this jumper wire. At this point look in your owner's guidebook to locate the two appropriate pins to attach to. If you have a controller or are making use of a fireman's switch this is where your control should be connected. If you have a controller and it is not attached here, it could be the source of your problems and also either have a qualified tech correct the problem or fix it yourself.

You must be careful not to place the jumper wire on the power terminals or you will damage your heater by burning up the electronic system. Usage your handbook to locate where the firefighter's switch is expected to be connected and thoroughly affix your jumper between these terminals. If you now activate the power and the heating unit works with no issues, your problem depends on the controller or the wiring visiting the controller. You will have to difficulty shoot this device.

If you still have the very same problem with your heating unit. (“solution heating system” light comes on), leave the jumper in position as well as validate that the pump is on which you have good water circulation. Make sure again with your meter that the pressure switch is not cycling. It should review as a dead short. (See segment one) With good water flow confirmed as well as the “solution heating unit” light on, your problem can be one of the thermo-regulators in the safety and security device.

Given that we started this with the indication light on the board lit next to HLS, the very first factor we are going to inspect are the wires visiting the high limitation button. The higher limit switch is found near all-time low on the left side of the water manifold as you admit. To see it you have to eliminate the side cover on the water manifold. The screw that holds the cover is on the top of it. You should make sure that the orange cords going to the switch are in one piece, attached and not rusty. If the wiring is good, use your multi-meter to examine that the high restriction button checks out as a dead brief. If it reviews open and the water is not over 104 F, replace the higher restriction switch. If this does not repair your problem you could have a bad control board and it will certainly need to be replaced. Testing the control board is a very involved process as well as will certainly be handled in a later section.

This is the end of section two as well as has actually taken you with part of the security circuit in the heater as well as 2 of the sign lights on the board. We will advance with our methodical diagnose of issues on the Sta-Rite swimming pool as well as health facility heating system in the following section.
